Answer:

0.22 atm

Explanation:

The total pressure is the sum of the partial pressures.

P = P₁ + P₂ + P₃

1.25 atm = 0.68 atm + 0.35 atm + P

P = 0.22 atm

Answer:

0.22 atm

Explanation:

First, you need to add up each of the values of the known gases

0.68+0.35

Then you need to subtract that value from the total pressure to find the partial pressure of the third value

1.25-(0.68+0.35)

By doing that you get the answer of 0.22 atm

liberstina [14]

Moderate alcohol consumption is no more than $One$ alcoholic drink(s) daily for adult women and up to $Two$ drink(s) daily for adult men.

What is an alcohol?

Alcohol is an organic compound containing a hydroxyl group and a carbon atom; Alcohol can be an intoxicant found in alcoholic beverages.

An alcoholic drink (also called an alcoholic beverage, adult beverage, or simply a drink) is a drink that contains ethanol, a type of alcohol that acts as a drug and is produced by fermentation of grains, fruits, or other sources of sugar.

The consumption of alcoholic drinks, often referred to as "drinking", plays an important social role in many cultures. Most countries have laws regulating the production, sale, and consumption of alcoholic beverages.

So, according to the scientific studies, the alcoholic consumption for women in a day is not more then one and for men is not for two drink(s)

0.785 moles of N2,fill a balloon at 1.5 atm and 301 K.<br> What is the volume of the balloon?

Tcecarenko [31]

Answer:

V = 12.93 L

Explanation:

Given data:

Number of moles = 0.785 mol

Pressure of balloon = 1.5 atm

Temperature = 301 K

Volume of balloon = ?

Solution:

The given problem will be solve by using general gas equation,

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Now we will put the values.

V = nRT/P

V = 0.785 mol × 0.0821 atm.L/ mol.K × 301 K / 1.5 atm

V = 19.4 L /1.5

V = 12.93 L
